Prof. Dr. Barbara Wessner, Deputy Head of the Centre for Sport Science and University Sports (University of Vienna, Austria), runs an analytical laboratory which aims to study the impact of exercise and nutrition on skeletal muscle function. Thereby, research questions and methodologies from the traditional field of Sport Science are merged with those from Nutritional Science and Molecular Biology. Her research output derived from the Vienna Active Ageing Study contributed significantly to unravel some of the molecular signatures associated with age-related muscle loss. Current projects focus on acute and chronic exercise studies to alter intramuscular connective tissue in young and old adults.
